One of the common problems with Power windows that you hear the motor running but the window will not go up is in the motor gear box. There are little plastic disc that wear out . Here is a very good link that is for this issue that one of the guy's on this forum posted. From your description I would check this first. It really is not a very hard job to do.

Hope the helps, '92
